AC•THOR®/ AC•THOR®9s Operating instructions, version a0020806 4

Before placing into operation it is essential to read the assembly instructions provided with the

device.

Commissioning takes place in a few steps and must be carried out when the AC•THOR is started for

the first time or after resetting to factory settings.

Use the left and right arrow keys to see more options.

From firmware version a0020202 onwards, French or Spanish can be selected in addition to German

and English.

See chapter headed "Operating modes".

The selection can also be changed at a later date.

Use the left and right arrow keys to see more options.

Besides the my-PV Meter and open communication protocols such as http, Modbus TCP, Adjustable

Modbus RTU and Adjustable Modbus TCP, as well as frequency control, pre-set signal sources are

available for many compatible manufacturers.

For certain compatible partners the choice between „Auto“ (automatic IP-search of the device) or

„Manual“ (manual entry of the IP address of the source) is possible. If a control type with the

addition "Manual" is selected, the next step is to set the IP address of the signal source.

In the case of a control mode with the addition "Manual", the IP address of the signal source

must not change during operation (e.g. by a DHCP router), otherwise the AC•THOR will lose the

control signal.

Growatt connection assignment for RS485:

Note: Inverters that are not SPH-UP may need to be updated to the latest

firmware version to communicate via RS485, according to Growatt. To do

this, send the Growatt serial number and a short explanation to

[email protected].

The control signal is received via Modbus RTU (RS485, A B GND)!

Connection diagram according to chapter 9.

When controlling via Modbus RTU, the operating mode M7 cannot be used!

If the Huawei Smart Dongle is used on the inverter, communication

problems may occur with this type of connection. We therefore recommend

using the control type "Huawei (Modbus TCP) Manual" if possible, especially

if a battery storage unit is present!

Huawei (Modbus TCP)

Manual

LAN

(RJ45, Ethernet)

Works with Huawei devices that communicate via Modbus TCP, such as the

Huawei Smart Dongle-WLAN-FE!

Note: From dongle firmware SPC124, TCP must be activated locally via the

Huawei app!

Alternatively, the AC•THOR could also be controlled via Modbus RTU. If a

battery storage is available, however, the "Huawei (Modbus TCP) Manual"

must be used explicitly!

This control type is available for the SMA Energy Meter and SMA Sunny

Home Manager devices.

If this control type is carried out by the Sunny Home Manager, the

superordinate energy planning for the my-PV device is then not given. There

is also no visualization in the Load Balance. However, the power control is

then carried out significantly faster than with the control type "SMA Home

Manager".

SMA Home Manager

LAN

(RJ45, Ethernet)

The power signal which the SMA Sunny Home Manager gives the my-PV

device depends not only on the feed-in, but also on the superordinate

energy planning.

With Modbus control, the excess power control can be selected according to

one or three phases.

TIP: For many of these and other manufacturers there are separate instructions

for the required settings. More information about compatible manufacturers can be

found here.

When controlled by an inverter, a feed-in meter is required in the system. The query of the

inverter otherwise provides no data.

AC•THOR®/ AC•THOR®9s Operating instructions, version a0020806 7

We ask for your understanding that we cannot do any binding support for third-party

products. For questions about third-party products, please contact the technical support of the

respective company.

Not every signal source is approved for hybrid systems with battery storage. If necessary,

please contact the technical support of my-PV.

Operation with battery may require additional control parameters. In this case, please contact

the technical support of my-PV.

A number is assigned to the sensor in the order in which it is selected. The selection can be

deselected by tapping on the key once more.

To assign a sensor to the respective entry in the list, the serial numbers can be identified on a label

attached to the sensor wire.

TIP: As the measuring value of the sensor is already shown in the selection

list, an assignment can alternatively also be made by simply altering the

temperature on the sensor.

TIP: The use of a sensor is not necessary if the optional boost backup or

the legionella programme are not used and the heat generator is switched

off by a thermostat!

By saving the settings the commissioning for the use of excess power is finished.

Additional functions, such as the optional boost backup, must be set separately.

AC•THOR®/ AC•THOR®9s Operating instructions, version a0020806 8

The "Home" button always returns you to the home screen. The upper bar shows the current date,

time, the unit number und the operating mode (mode M1 –Mx). On the right, symbols show the

unit's current status.

The contents of the home screen vary according to the operating mode and shows how much power

the AC•THOR is currently feeding into the load. Depending on how many, if any, temperature

sensors are defined, the measured values are also shown.

The button "Single boost" only appears in hot water operating modes if the function for

ensuring a minimum temperature is activated. Actuating the button starts a once-only

boost backup mode. This can also be deactivated while it is in operation.

If the boost backup is actuated automatically based on the day of the week, time of day or

temperature, it cannot be deactivated by using the button.

Recorded production data, meter values and temperatures can be read off at any time. The

respective values can be selected using the "Open" button. These can be presented in the three

views of the current year, month or day using the "Calendar" button.

TIP: Type directly in the diagram on the individual bars to present the data in their

next level of definition and on the button of the data logger again to return to the

previous level.

The following data can be displayed:

Total power: Shows the total power figures for all the connected loads. The yellow bars indicate the

PV excess power used, the green bars the proportion of grid energy when the optional temperature

boost backup is active.

Meter: indicates the value of the total power drawn from the grid (red) including household loads

and grid feed-in (green) at the metering point.

With AC•THOR 9s, the load status (0 or 1) at the three outputs is displayed at this point.

If "none" or "0" is displayed even though a load is connected, the cause may be a thermostat that

has been switched off or a safety temperature limiter that has been triggered.
